Linuxfabrik FirewallFabrik¶
Modern successor to Firewall Builder: Qt GUI for managing iptables/nftables policies. Centralized policy DB with reusable objects, scales to hundreds of firewalls, generates deployment-ready shell scripts.
Made by Linuxfabrik.
Overview¶
FirewallFabrik is a modern successor to Firewall Builder, preserving its core design philosophy while updating it for current firewall technologies. It is a Qt-based GUI that manages firewall policies for multiple platforms, including iptables and nftables, from a single unified interface. All objects, rules, and device definitions are stored in a centralized policy database, allowing consistent reuse of services, networks, and rule sets. This architecture scales cleanly from a handful of devices to hundreds of firewalls, all managed from one policy file and one UI, with platform-specific configuration generated automatically.
